Owning a smart scale from Xiaomi opens up access to detailed analytics of the body’s state, but users often find that the display displays only weight, which is because the device shows the basic parameter by default, and access to Body Composition requires primary synchronization with the smartphone. Without this step, the gadget operates in normal weight mode, ignoring the built-in bioimpedance analyzer.
To access fat, muscle and bone mass data, you need to link the scales to a Mi Fitness or Zepp Life app via Bluetooth, which is when the calibration and transfer of the user profile takes place, allowing the algorithms to calculate fat percentage based on tissue resistance to electric current. The primary connection process is a critical step, without which further measurements will be incomplete.
In this article, we will break down a step-by-step algorithm that will help you activate all the functions of the device. We will look at the nuances of profile settings, analyze common connection errors and explain why data may not be displayed immediately after weighing.
The principle of operation of bioimpedance analysis
The technology used in the Xiaomi Mi Body Composition Scale is called bioimpedance analysis, which sends a weak, completely safe electrical signal through the human body, because muscles contain a lot of water and electrolytes, they conduct current well, and fatty tissue, which is characterized by a low water content, creates high resistance.
Based on the resistance data you get, and the parameters you enter (height, age, gender), the built-in algorithm calculates the approximate body composition. The accuracy of the measurements depends on the quality of the stops' contact with the electrodes and the correctness of the anthropometric data entered. If you are standing wrong or the feet are dry, the signal can be distorted.
It's worth noting that the result of measuring fat percentage can vary depending on the time of day and the body's water balance, and to get the most objective picture, experts recommend weighing yourself on an empty stomach in the morning, immediately after waking up, this minimizes the influence of external factors on the electrical resistance of tissues.
💡
For better electrode contact, slightly moisten your feet before weighing if the room is very dry.
Preparation for the first connection
Before you get on the scale, you need to prepare the software. Make sure your smartphone has the current Mi Fitness app (formerly Zepp Life) or Xiaomi Wear, depending on the weight model and region. Older versions of the software may not display new metrics correctly or support synchronization.
Turn on Bluetooth on your phone and make sure that fresh batteries are inserted into the scale. A weak charge of the batteries can cause the scales to show weight, but they can not transmit body composition data due to lack of energy for analysis. Also check that the surface on which the scales are standing is solid and flat.
It's important to create or log in to your Mi Account inside the app, and all your health data is tied to that profile, and if you're planning to use scales with your whole family, each family member should have a profile in the app so that the algorithm can correctly calculate the percentage of fat based on individual parameters.
- 📱 Install Mi Fitness or Zepp Life from the official store.
- 🔋 Check the battery charge and density of their fit in the compartment.
- 📶 Enable Bluetooth and geolocation on your smartphone to find your device.
- 👤 Register with Mi Account and fill in your age and height details.
☑️ Pre-launch check
Step-by-step instructions for synchronization
The setup process takes no more than two minutes, but requires a sequential execution of actions. Open the app on your smartphone and go to the add-on section, usually a plus button or the "Add-device" item at the top of the screen.
Stand on the scale with your bare feet. The weight numbers should light up on the display, and then a flashing Bluetooth indicator or connection icon will appear. At which point the phone should detect the scales. Click on the model name in the list of found devices.
Once paired, the app will ask for confirmation, make sure the user profile correctly lists gender, height and date of birth, which are the parameters used by the formula to calculate fat percentage, and if the data is wrong, the calculation will be wrong, even if the scales themselves work properly.
| Parameter | Impact on calculation | Where to change |
|---|---|---|
| Growth | Critical for BMI and % fat | User profile |
| Age. | Affects metabolism | User profile |
| Paul | Different formulae for calculation | User profile |
| Type of body build | Adjustment of the rule | Profile settings |
💡
The first connection must necessarily occur with the running application on the phone, otherwise the scales will not store calibration data.
How to measure the results
Once synchronized successfully, the weighing process becomes automatic, and you just have to stand on the scale, wait for the weight to be fixed, and the "ok" or flashing data symbol to appear, and the smartphone next to you will automatically pick up the result.
Open the app to see detailed statistics, and here you'll find not only weight, but also a graph of changes in percentage of fat, muscle mass, water levels and bone tissue, and the data is sorted by date, so you can track the dynamics of changes over the long term.
If you use a scale with the whole family, the app automatically recognizes the user by weight and distributes the data to the appropriate profiles, however, to initially set up each new user, it is recommended to weigh with the application running, selecting a specific profile manually.
Why don't the data appear in the app?
Weighing mode without phone
Many users are wondering if you can find out fat percentage if the phone is not nearby. Xiaomi scales have built-in memory that can store data on the last 10-16 weigh-ins. However, to see exactly the percentage of fat, the initial setting with the phone is still necessary.
Once you have your profile memorized, you can stand on it without your phone, and the device will only show the weight on the display, but internally (inside the memory) it will perform a full body composition analysis, and the next time you open the app and go to the scales, all the data stored will be synchronized.
It's important to understand that without first synchronizing the scales can't calculate the percentage of fat, because they don't have data on your height and age, and in this mode, they'll work like a normal mechanical device, displaying only body weight.
- 📉 Libras can remember up to 16 last measurements without a phone.
- 🔄 Synchronization occurs automatically when you open the application next to you.
- ⚠️ Without reference to the profile, the calculation of the body composition is impossible.
Addressing common problems
Sometimes users are faced with a situation where the scales show weight, but the percentage of fat is not calculated or a dash is displayed. Most often this is due to the fact that the scales did not recognize the user. Try weighing yourself with a phone running the application to force the synchronization.
⚠️ Attention: If the scales show a measurement error, make sure you stand flat, don't move, and your legs don't touch each other.
Another reason could be a Bluetooth smartphone malfunction, which is to try to forget the device in your phone's Bluetooth settings, remove the scales from the app, and re-pair, often solving problems with bioimpedance data transmission.
If the scales show clearly incorrect values (for example, 3% fat or 60%), check if the application is included in the "Infant Weighing Mode" or "Breasure Weighing Mode", these modes turn off body composition analysis and change the algorithm of the sensors.
